I've heard alot about it and aparently people were waiting a long time for the servers to open, Friends have asked me to play it with them and from other friends i've heard that they are currently playing on it with minimal queue time.
From what I hear, the Queue time on the busiest server (EU one) with 1k people in Queue was 15 minutes.
I would try it out when I would have some more time and when the queue's go down a bit, as if i remember on ArchAge you had to Queue for over an hour only to get into the game.
I've seen twitch streamers play B&S during the pre-release for paid users and it does seem indeed a very nice game, well design'ed and lots of efford put into it.
